sidebar appears below the content

After step 3, the sidebar is below the content. The sidebar has float:right and widht: 23% in my css so, this is not the problem. The content width is correct, too. I dont know where is the problem, please, nobody can help me?

or something like that. You need to check the structure of your theme in a page where your sidebar is displayed correctly, and then modify the template files BPTP copied to your theme to reflect that structure.
